From the wealth of experience in here, I'm curious, what's the longest you've seen a mouth sore hang on after treatment? During treatment, Vince was fortunate to be able to keep the mouth sores under control using a combination of washes; hydrogen peroxide/water, caphasol, mugard & pink stuff. He finished Aug 31 and has recovered amazingly well since, back to work in Oct, already logged 2 int'l business trips. The only real residual issues he's having are the dreaded dry mouth, some swallowing issues (headed to U of C today for a swallow study) and a mouth sore on the side of his tongue that will not heal. We're not worried about it being something bad, the docs have had several good looks at it, but he's wondering when he can expect it might heal. Any thoughts?
